Automatic controller add via dialog

[snupo]

When I start my MacBook and Maschine MK3 controller, which is my audio interface, MacBook always starts without this controller / audio interface. After a few seconds I always got a dialog saying like

found new hardward MK3
- add ?
- other option i dont remember
- ignore ?

I always clicked yes. After a while I clicked ignore, hoping that in the future it would automatically add. Wrong thinking, bad idea. Now I no longer get the dialog and need to step into the audio settings on every start.

I cannot find a setting where I can bring back this dialog. Anyone knows how to get the dialog back?
